Answer:2

Step-by-step explanation:

Answer:

a is 3x-3+1=3x-2 B is -1-y+3+y=2 C is -x+x+2 = 2

Step-by-step explanation:

a has 3 positive x's and 3 negative ones and 1 so the equation is 3x-3+1 and to  simplify you would do -3+1 which is 2 and 3x is simplified enough so a is 3x-3+1=3x-2

B one negative 1 and 1 negative y 3 positive ones any one positive y. so the equation is -1-y+3+y and the answer is 2 everything elese cancels out.

C  one negative x one positive x and 2 positive ones so the equation is -x+x+2 and when you simplify you get just 2 again.

If you need any help or further explaination leave a comment or if its wrong tell me and ill try my best to fix it.

Answer: 28.6%

Step-by-step explanation:

To calculate the percent error:

1) Subtract the estimated amount by the actual amount

45-35=10

2) Divide the answer by the actual amount

10/35=0.2857

3) Multiply the answer by 100 to get the percent error

0.2857×100=28.57

Rounded that equals 28.6%

Answer: hope this helps ♡

The percent error for the park sign's estimate is 29%.

Step-by-step explanation:

45 - 35 = 10

(10 out of 35 because it's the actual amount)

10 of 35 in percentage:

(10 ÷ 35) × 100 =

0.28571..... × 100 =

Answer:

The smaller integer is 4 and larger integer is 8 .

Step-by-step explanation:

First we have to form own variables and expression. So we let the smaller integer be x and the larger integer be y. Next using the information given to form expressions :

\(x + y = 12 \\ 5y - x = 36\)

Lastly, we can solve the simultaneous equation using Elimination :

\(x + y = 12 - - - (1)\)

\( - x + 5y = 36 - - - (2)\)

\((1) + (2)\)

\(x + ( - x) + y + 5y = 12 + 36\)

\(6y = 48\)

\(y = 8\)

\(sub \: y = 8 \: into \: (1)\)

\(x + 8 = 12\)

\(x = 4\)

Answer: 858.55 in

Step-by-step explanation: You calculate the area of the triangle ( 22.3 x 15.4/2), then you multiply the result by 5.

Answer:

858.55

Step-by-step explanation:

Area of triangle = 1/2BH

1/2(22.3*15.4) = 171.71

Because there is five sides on the pentagon we have to multiply the 172.71 by 5 to get the final answer.

171.1(5) = 858.55

Answer: Read below.

Step-by-step explanation:

\(3x+17<47\\-6x+9<25\)

Let's take the first one.

\(3x+17<47\)

Subtract 17

\(3x<47-17\\3x<30\)

Divide by 3

\(x<\frac{30}{3}\\ x<10\)

---------------------------------------------------------------------------------------------

Now the second one.

\(-6x+9<25\\-6x<25-9\\-6x<16\)

Here's the trick. You need to divide by -6; however, there's a rule. When you multiply or divide by negative numbers, the inequality sign flips.

\(x>\frac{16}{-6}\)

\(x>-\frac{8}{3}\)

---------------------------------------------------------------------------------------------

x has to be less than 10

x has to be greater than \(-\frac{8}{3}\) or -2.66 approximately.

in the number line, make a hollow circle on \(-\frac{8}{3}\) and draw an arrow up to \(10\) where, again, you have to make a hollow circle. The circles have to be hollow because neither \(-\frac{8}{3}\) nor 10 are part of the answers.

Answer: 36 inches (in.)

Step-by-step explanation:

The first thing you need to do is form a right triangle from the starting point to the hole to the corner where the ball is at. Right triangles have a hypotenuse (the longest side), and two legs (the shorter sides).

We are told next to the drawing that it’s 39 feet from the staring point to the hole (given a straight line). This is the length of our hypotenuse. We are also given the length of one of the legs, with it being 36 feet.

We need to find the length of the last leg, the length from the ball to the hole. To do this, we can use the Pythagorean Theorem. The Pythagorean Theorem states that the square of each of the legs equals the square of the hypotenuse. The formula for the Pythagorean Theorem is \(a^{2} +b^{2} =c^{2}\), with \(a\) and \(b\) being the legs, and \(c\) representing the hypotenuse.

Input the given values into the formula and you get the following:

\(a^{2} +b^{2} =c^{2}\)
\(36^{2} + x^{2} =39^{2}\)

\(\sqrt{36^{2} } +\sqrt{x^2} =\sqrt{39^2}\)

\(36 +x =39\)

\(x=3\)

Therefore, the length from the ball to the hole is 3 feet (ft.).

BUT WAIT
The question asks us to provide our answer in inches (in.), and 1 foot equals 12 inches.

Therefore, the distance from the ball to the hole is 36 inches (in.).

1 month is aprox. 30 days, so

To find john's daily salary:

For a month, the salary is 4,410 rupees, so for a day how much?

days     salary

30          4,410    (This is how I learnt to solve these kind of problems)

1               ?

Then you crisscross the equation which becomes

4,410/30=147 rupees

To find weekly salary:

we now know the salary for one day so we can say: For a day, the salary is 147 rupees, so for 7 days (1 week) how much?

You multiply the salary for one day and the number of days: 147×7=1,029 rupees

To find salary for a year (annual):

we now know the salary for one day so we can say:  For a day, the salary is 147 rupees, so for 365 days (1 year) how much?

You multiply the salary for one day and the number of days: 147×365=53,655 rupees

Answer:

The first option, V ≈ 1607.7 in²

Step-by-step explanation:

Find the volume of the given cylinder.

\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)

Given:

r = 8 in

h = 8 in

π = 3.14

Find:

V = ?? in³

\(\hrulefill\)

Now solving,

Substitute the given values into the formula:

=> V = (3.14)(8)²(8)

Using a calculator to simplify:

=> V = 1607.68 in²

Rounded to the nearest tenth:

∴ V ≈ 1607.7 in²

Thus, the first option is correct.

Step-by-step explanation:

The options 1,2 and 5 are the correct answer.

The given equation is 1.23/\(10^1\)=0.123.

The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.

Now,

1) 1.23/\(10^1\)=0.123

Here LHS=RHS

2) 123/100=1.23

Here LHS=RHS

3) 12.3/\(10^0\)=1.23

⇒ 12.3/1=12.3

So, LHS≠RHS

4) 0.123/10=1.23

⇒ 0.123/10 = 0.0123

So, LHS≠RHS

5) 1230/10³=1.23

⇒ 1230/1000

= 1.23

Here LHS=RHS

Therefore, the options 1,2 and 5 are the correct answer.

Answer:

This example represents discrete data.

Step-by-step explanation:

Discrete data refers to information that can only take certain specific values. In this case, the number of pamphlets added to the box (x) can only take on integer values such as 0, 1, 2, 3. Similarly, the effect on the box's weight (y) is also given as specific values: 0, 6, 12, 18.

In contrast, continuous data would involve measurements that can take any value within a range, such as height, weight, or temperature.

Since the number of pamphlets added and the corresponding effect on the box's weight are presented as specific, separate values, the data in this example is considered discrete.

Step-by-step explanation:

Answer: The total percentage decrease in the investor's stock account is 34%

Step-by-step explanation:

The investor's stock in Company A= $3800

The investor's stock in Company B= $3400

Percentage decline in stock of company A= 22%

Decline in value of stock of company A= 3800× 22/100

= 38×22

= $836

Percentage decline in stock of company B= 3400×12/100

= 34×12

=$408

Total decline in wealth of investor= 836+ 408

= $1244

Total percentage decline in wealth= 1244×100/7200

= 124400/7200

= 17.27%

The percentage decrease in investor's stock is 17.27%
